MACHINE FOR WASHING PRINTERS FURNITURE.

To all whom t may concern.'

Be it known that I, FREDERICK W. STEINER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Machinesfor Washing Printers Furniture, of which the following is aspecification.

My invention relates to improvements in machines for washingprinters-furniture.

One of the objects of my invention is to provide a machine that willthoroughly and quickly wash printers furniture, such as slugs, rules,etc., and which will provide a substantially gas tight closure for thevery volatile detergent used to cleanse the articles, such as benzin,gasolene or the like, thereby to reduce the danger of ignition andexplosion.

Another object of my invention is generally to improve machines of thischaracter,

` to cheapen 'the cost of production; to render them self-draining andto simplify their construction. j

Other and further objects of my invention will be readily understoodfrom the following description when taken in conjunction with thedrawings, wherein Figure 1 is a side elevation of the machine withl thetop raised and the cylinder in position to be opened, to admit thematerial to be cleansed. Fig. 2 is a central, vertical section, taken online 2-2 of Fig.- 1. Fig. 3 is a transverse section taken on line 3 3 ofFig. 1. Fig. 4 is a section taken on line 4 4 of Fig. 1. Fig. 5 is anaxial section of a fragment of the drum. Fig. 6 is a sectional detailportion of the body part, and a portion of the top, showing means forholding the top open.

In all the views the same reference characters are employed to indicatesimilar parts.

The main body part of the structure is composed of fourl substantiallyvertically disposed angle irons 10, deiiected near their bottom, as at11, to provide feet and having attached to their sides three fixedpreferably sheet metal side walls 12, 13 and 14. Secured to the openside of the structure are two swinging doors 15 and 16 hinged, as at 17,and provided with a latch 18 to hold the doors together when they areclosed. A

Specification of Letters Patent.

` 29, for engagement with the shaft.

semi-cylindrical top 19, is hinged to the side wall 13, as at 20, andwhen down in position ltpoverhes the upper portion of the rotatable drum21.

'A slotted bar 22 is pivoted to the top, as at 23, and is provided witha slot 24, which includes the pinf25 that projects inwardly from thewall 12 Iof the structure. The bar 24 and the slot are curved laterallynear the bottom end, as shown in Fig. 1, so as to engage the pin 25 forretaining the top 19 in ralsed position.

The drum 21 is provided with two heads 26, which are substantialduplicates, and which are securely mounted on the shaft 27, as by meansof pins 28--28. Each head is provided with an inwardly projectin hubcircumferential wall 30 is secured to the outer periphery of each of theheads 26, and a wood lining 31, is perforated with holes 32 thatregister with similar holes in the sheet metal wall 30. The woodlining'is placed in the circumferential groove, between the wall 30 andthe inner annular flange 33 projecting from the head 26.

A door 34 is adapted to be slid outwardly from the drum to provide anopening for admission of material within the drum. When the drum is inthe osition shown in Fig. 1 with the top 10 raised the door 34 may bemoved laterally without interference of any of the other portions of thestructure.

Bearings 35 are provided in the vertical walls of the body portion ofthe structure for the ends of the shaft 27 and one end of the shaft 27is fitted with a geared pinion 36 which meshes with the gear wheel 37that is rotated by means of a handle 39 to rotate the drum. A protectinghousing 40 covers this train of gearing.

A semi-cylindrical tray 41, is normally in the bottom of the bodyportion of the structure, and when lifted it is adapted to receive thelower portion of the drum 21. Each corner of the tray is provided with aguide comprising a short piece of angle iron 42, adapted to slide withinthe corner angle irons 10 when the tray is being lifted. Projectinglaterally from each side of the tray are studs 43 to which liftingcables 44, on each side of the tray are connected. The

,and is provided with a handle 52, by. means of which(4 the pawl may belifted from the ratchetw'heel. A spring 53 normally holds the pawl inengagement with the ratchet wheel. When the handle 48 is turned, inclockwise direction, the cables 44 are wound upon the drums -46--46 andthe tray 41 is raised until the detergent, contained therein, passesthrough the perforations `32 made in the cylindrical walls of-the drum,the ratchet wheel and pawl hold the tray in elevated position. Now whenthe handle 39 is rotated the drum 21 is rotated within the tray 4l andthe articles contained in the drum are thus moved yin the liquiddetergent and thus the cleansing operation is performed. After the drum21 has been rotated sufficiently to cleanse the articles the tray 41 maybe lowered by pressing upon the handle 52, controlling the pawl 53 so asto release the ratchet wheel 49, when the handle 48 may be turned to theleft and permit the tray 41 to descend to its lowermost position. Afterthis has been done the articles contained within the drum 21 will drainand the surplus Huid will fall back into the tray 41.

It is very essential that the doors 15 and 16, of the casing be closedand that the top 19 shall be down to close the open end of the casing,when the drum 21 is being revolved in the detergent contained in thetray 41, and for this purpose I provide an automatic means for closingthe door by the movement of the top19. To this end I provide on eachside of the top 19 a rod 54, which is pivotally connected to the point53 of the top, which extends any convenient distance down the side wallsof the casing, to the lower end 55 of which is cpnnectedla cable 56,that passes around a guide pulley 57 and is connected by its free end toa bracket 58` projecting from the respective door. A spring 59, which is.connected to one of the legs 11 and to the bracket 58, normally holdsthe respective door in closed position. When the top is' raised,^thecables 56-56 are raised, which pulls upon the brackets 5 8--58 againstthe operation ofthe springs 59-59 and causes the doors to open. When thetop is. lowered the springs 59-59 will be free to operate the respectivedoors and therefore the doors Will thereby be closed;

by the eii'ect of the springs the drum 21 will be included in aperfectly gas tight nclosure, when the top is lowered, while the gas isevolved by agitation of the detergent during the process of washing.

To drain the tray of the detergent that is no longer useful `I provide astop cock 60, fixed to the lower part of the tray and a lip 61, thatextends through the casing 12 and under the stop cock so that when thecock is ened the fluid from the interior of the tray will be-received bythe lip 61 from which it may How into a proper receptacle.V To closetheopening in the lip 61, I provide a shutter, or door 62, pivoted as at63, and provided with a lifting knob 64. When .the device is not inoperation the volatile detergent is protected from danger of fire andloss by evaporation.

1 have 'described a specific structure to disclose my invention but itmust be understood that departure from such embodiment may be made inthe configuration and disposition of the parts within the scope of theappended claims.

Having described my invention, what I claim is 1. A machine of thecharacter described comprising a perforate drum; aI closed 'casingstructure, upon which the drum is mounted; a semi-cylindrical tray forcontaining a detergent mounted within said structure below the drum andmeans for relatively moving said tray and drum to s include the lowerportion of the drum within the tray.
